Sorry I can't furnish pictures Masie, but perhaps the following will help. The Boysenberry is a scarcely-cultivated fruit, believed to be a hybrid of Loganberry, Raspberry and the Pacific Blackberry.
Treat it as a Blackberry. It is best grown on a trellis or along taut wires. Fully hardy it will reach an eventual height of 1.5m. It is happy in most growing conditions, and the large reddish-black fruits are rich in vitamins.
